Formula Used
The calculator uses basic arithmetic operations to compute the result:
Where:
- a is the first decimal number
- b is the second decimal number
The calculator handles both positive and negative numbers correctly, following standard mathematical rules for decimal arithmetic.
Worked Examples
Example 1: Addition
Calculate 3.5 + (-2.7):
The result is 0.8, which is positive because the absolute value of the first number is greater than the second.
Example 2: Subtraction
Calculate (-4.2) - (-1.8):
The result is -2.4, showing how subtracting a negative number is equivalent to adding its absolute value.
Example 3: Multiplication
Calculate 2.5 × (-3.2):
The result is -8.0, demonstrating that multiplying a positive by a negative number yields a negative result.
Example 4: Division
Calculate (-6.4) ÷ 2:
The result is -3.2, showing that dividing a negative number by a positive number preserves the sign.
Interpreting Results
When working with negative and positive decimals, keep these key points in mind:
- Adding two negative numbers results in a negative number.
- Subtracting a negative number is the same as adding its absolute value.
- Multiplying two numbers with opposite signs yields a negative result.
- Division of a negative number by a positive number preserves the negative sign.
The calculator will always show the correct sign based on these mathematical rules. If you're unsure about the result, double-check your inputs and the operation you selected.
